我国部分地区居室氡浓度水平调查研究

Abstract

Abstract: The paper reports the method and main results of investigation on radon in dwellings in some parts of China. Measurements of indoor radon concentrations were performed in one province and seven cities for one year, with every 3 months for one period, corresponding to spring, summer, autumn and winter seasons, using solid state nuclear track detectors. It involves 2 029 dwellings in total, and the population of the cities accounts for 12% of China. The investigation shows that the range of indoor radon concentrations is 5.3—183.0 Bq·m^-3, the average values with sample-weighted and population-weighted are (32.6±5.2) Bq·m^-3and (30.7±4.3) Bq·m^-3respectively. Radon concentrations in dwellings with different building ages, types and materials in urban and rural areas were compared in this paper, and seasonal variation of radon in dwellings were compared also.

Key words: indoor, radon, investigation, comparative analysis, NORM
